As mentioned in Utah Station Bulletin No. 124, seepage conditions on the Southern Utah Experiment Farm were responsible for the removal of about 5 acres of vineyard in 1908, and 7 acres of mixed peach orchard in 1910, all of which were on the lower or western half of the farm.
These orchards and vineyards had always received good care, clean culture being practiced in fact as well as name. The results for a number of years were all that could be desired, when the trees and vines began to die questions arose as to the cause: since in spite of a reduced number of irrigations the trouble grew rapidly worse. Before removing the orchard in 1910 two lines of investigation were undertaken. The purpose was to gain some idea of the conditions then existing in the soil and further to determine how these and other possible conditions had caused the trees and vines to die.
